Letters Patent No. 114,378, dated May 2, 1871. Y

IMPROVEMENT IN COMBINED SQUARE, BEVEL, PLUMB, AND GAUGE.

The Schedule referred to nithese Letters Patent and making part o! thelame.

To all whom tt may concern l Beit known that I, MILTON M. WILSON, ofElwood, county of Atlantic, State of New Jersey, have invented a new andimproved Combination Tool, and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe accompanying drawing and to the letters of reference marked thereon.The object of my invention is to provide a combination tool that willembrace a rule, marker, try-square, gauge, bevel, spirit-level, andplumb, which is especially adaptedvfor carpenters use inweather-boarding a building.

Figure l of the drawing is a side view of my improved combination tool.

Figure 2 is a top view of the same.

Figure 3 is a side view of the same, showing the gauge'partiallyextended and theinstrument adjusted .for a try-square.

To enable those skilled in the art to make and use my invention, 1 willnow proceed to describe it.

The hody of the tool consists of a wooden bar, B,

the central portion of which is made somewhat nar-V rower than the endpieces E and E', so that it can be placed on an angle or transverselyacross a board and used as a marker.

On the upper edge of the bar B is secured a metal strip, S, on the faceof which are marked the ordinary divisions of a foot-rule, and in oneend of the bar and sliding under the said strip is an adjustable gauge,G, the upper surface of which is also marked with graduated inches.

' not in use, is closed down in a suitable slot formed in the bar, andwhen elevated in a vertical position it can be used as awry-square; orit can be placed onany angle desired and used as a bevel in cuttingmiters, Sac. i p

The slot O, through which the thumb-screwT passes, allows the blade tobe extended or shortened to different lengths above the upper edge of'.the bar B.

A projection, J, secured tok the netal strip S, at a proper distancefrom that end of the bar into which the gauge Gr is passed, is pressedagainst one edge of the board when the gauge is set for a certain-width,

or for marking the position of the nails in weatherboarding.

In the center of the bar B is placed a spirit-level,

l L, which is visible through a rectangular-shaped opening made in themetal strip S, so that the instrument can be placed in a horizontalposition and used as an ordinary level.

VThe endpiece E' has a circular opening, N, made through'it, in which isplaced a spirit-level, L; the said level is set transversely across thebar B in order that,.. when the instrument is placed in a verticalposition, it will act as a plumb.

rlhe end pieces E and E are iucased ou the sides and lower edges withmetalpplates secured by screws, and the lower edge of the bar B is alsoprotected by means of a metal strip secured to it.

Having thus described my invention, its construe-1 tion and operation,

What I claim, and desire to secure by Letters Pateut, is-

The above-described combination tool embracing a rule, marker,try-square, gauge, bevel, spirit-level, and plumb, constructed-andoperating substantially as and for the purpose specified.

In testimony whereof- I have hereunto signed my name in the presence oftwo subscribing witnesses.

- MILTON M. WILSOR.
